Which will give you this: Text Here. Or, click the "url wizard" option above the text box when you're writing, and let that do it for you.

The formatting for this is completely off the standard for no apparent reason. I recommend looking at some conventional SCPs and seeing how they are set up. That along with the lack of clinical tone, you should read the How to Write an SCP guide, which has help with formatting and general advice for how to write a successful article.

The anomaly itself is not at all interesting. Talking dice could be interesting if done correctly, but as you have it here they're just friendly talking dice with no conflict or reason.

While not all that interesting as stated prior, let me break down some of the issues I see in this article for when you either revamp this or take a crack at another one. I'm not going to mention too much that's already mentioned already, and am instead going to focus on the tone and writing itself.

These dice are a regular pair of dice meant for the game Dungeons and Dragons.

How so? Polyhedral dice can be used for all manner of games - even outside of roleplaying games, they see use in board games and even gambling. Even if they're "Roleplaying" or "Battle" dice, that doesn't necessarily mean they're meant specifically for D&D, unless there's another reason as to why that's specified.
A more clinical wording would be something along the lines of "This is a set of polyhedral dice". You could even specify a manufacturer if you wanted to enforce their use as something for games.
The dice can't be a pair if it's a set of 7 different items. A pair is exactly two of the same thing.
The opener states they're a "regular pair of dice" but then it's immediately described afterwords how anomalous they are. "Appear to be a regular…" would work better if you're trying to enforce how much their non-anomalous properties are similar to real-world dice.

They are a purple with gold lettering.

I'm assuming you meant to include "dice" after "a" or meant to remove "a".

They come in D4, D6, D8, D10, D12, D20, and D100.

Not only is a d100 not shown in the attached image, d100 are not part of a standard set of polyhedral gaming dice. This is a d100. I'm assuming you are referring to the secondary d10 that has 2-digit numbers.
Additionally, a Skip that has more than one object usually has those numbered - like SCP-XXXX-1, SCP-XXXX-2, SCP-XXXX-3, etc. While the exact usage changes from writer to writer, the base SCP-XXXX is the group of objects, root object, or causing object/event, while SCP-XXXX-1 through whatever number is used to specify individual (or additional) objects in the group or resulting objects.
A clinical rewrite might look something like "SCP-XXXX is a collection of dice numbered SCP-XXXX-1 through SCP-XXXX-7." before you go into more detailed descriptions.

They can move on their own,

How? Like, really, how do they do that. Do they slide, roll, float, fling, teleport, sprout legs and move? Has the movement been observed, or is it concluded based on finding the Skip in a different position or area than left in?

These dice each have their own consciousness and personalities. […] and can feel pain, complex emotions

You can probably just boil this down to "are sentient". At the very least, these thoughts are related, and should be grouped together.

as well as communicate in all languages. Their communication seems to be able to be heard through any object.

As with the movement, how? Is this a telepathy observed/assumed to be coming from the dice, thoughts forming in a subject's own head as they witness it, or does it actually cause sound waves? Questions like this may seem tedious, but they really are things that would be sought answers for in a research facility.

They are somehow possible to “see” like a regular living being.

Not all living beings can see, and of those that can, not all can see in the same way. Some creatures have so many more cones for seeing color in the light spectrum than us that they can see colors we literally cannot possibly fathom to any degree. Does this sight appear to be based off of light? Is this sight affected by obfuscation?

They seem to have memories though,

Being able to recall data is not the same as possessing memories. Memory is usually something that is in a constant state of both write and read. You stated tests were done to determine this - what kind of tests were these?

which may be implied that at one time they had human forms and were either turned into or put into the dice.

Wild theories with no basis don't have much place in a research and analysis document. If this is something the dice themselves claimed, that also means there's no way to necessarily prove that. This information doesn't need to be removed altogether, but it should be clear that this information is not presented factually. If there's proof, that proof should then be included, but should speak for itself.

Since these dice are harmless and can only communicate, they do not need to be stored anywhere and thus they sit in a plexiglass case in the break room of Site-73. This is due to their social nature and need for communication with others. The plexiglass is merely there to prevent theft of the dice.

Are you able to conclusively state that the dice are 100% harmless?
You say they don't need to be stored, but then state a storage location.
Even if they don't "need" to be stored, the Foundation stores and archives everything. "Secure. Contain. Protect." This applies in more ways than just justification to wave around global conspiratorial power.
Is this need of social communication something the dice require or else they would "die"? Are the dice incapable of fulfilling this social aspect with each other? If "no" to either, they probably get put into storage or a containment cell.
Anti-Theft wouldn't be a "merely" issue for the SCP Foundation - it's one of its primary goals that, at least partially, dictates the cataloguing of almost every entry. Additionally, I don't know about you, but I find it pretty easy to break open plexiglass. You don't even really need tools for that. You could pretty much just punch it. What I'm getting at is: if some random Joe working at Site-73 wanted to get those dice, then, as is, he's getting those dice.

Voice of a mid 20’s caucasian female

As with the following entries… How is the age, race, or even gender known based on voice alone? Is the researcher who documented this assuming this, or did the dice state this? While race can influence tone, inflection, and volume of voice based on chest, throat, and face structural differences, this is just an influence, and not by any means a clear indicator. Age influencing voice mostly happens in early or late life. Gender can be assumed or implied in voice, but I've personally met many a woman that sounded like a man, and many a man that sounded like a woman. Unless the dice themselves stated their age, race, or gender or were asked that as part of an interview (something missing here that could also add quite a bit to the flavor of the article) I can only imagine a researcher marking down a gender, most likely noting it as a "masculine" or "feminine" voice for documentation.

and hates to be rolled. She’s kind and generous and will sometimes “help” the roller by moving to a higher number for them.

She'll help the roller… Even though she hates to be rolled. And she'll "help" the roller by moving to a higher number for them… Even if a lower number might be more beneficial.

She is shy, and also has the tendency to gossip and spread rumors.

As-written, this is very nearly an oxymoron. Also has no place in a clinical description.

She’s the one to go to if you want the latest trends or gossip.

Has no place in a clinical description as part of an analytical scientific document. If you want to get these personality quirks through, the best place to do that is either through interview logs or through notes of some form of researcher, maybe some type of psychologist. This is the same for all other personality quirks or personality descriptions. Remember: Opinions shouldn't really appear in the main part of the article.

voice of a caucasian teenage nerd

This and Thomas are the only ones missing a gender notation, although the name is often masculine I suppose. Even though I stated a problem with this not being explained properly earlier, scientific documentation should still be consistent - even when based on assumption.

voice of a young african-american girl

"Of African descent" would be more appropriate unless the die specified it was from America.

voice of a middle aged mexican man

"Hispanic" is the much more common racial nomenclature on the site. If this is referring to region, again, how does the Foundation know this?

She’s the comedian of the group.

Guy changes gender in the very last sentence. If this is intended, there's nothing stating nor clarifying that it is, or how the Foundation knows that.

Voice of a young-adult irish woman

You very suddenly switched to naming regions of origins two dice ago, but it's a bit more evident here. Again, consistency. If one of them is titled by their race, they all need to be. If one of them is titled by their region, they all need to be. The appropriate racial nomenclature here is still "Caucasian". The same can be said of "Thomas"

He is a complete pacifist and will try to convince you of doing only the right thing.

In the SCP, this is 100% subjective, and would be up to the interpretation of the die. Show "Tom" SCP-231, for instance. I'm sure he'll find it an enlightening experience as to what the "right thing" is.
